With the iGrow 800 you can program Temperature, Relative Humidity, and C02 Setpoints .

Please view the following video and necessary steps in setting up your sensors 

Cool Setpoint - if the temperature goes above this threshold it will enter into the cooling stages to bring the temperature back in line within the Normal temperature range (you can have up to 6 cool stages)

Heat Setpoint - if the temperature goes below this threshold it will enter into the Heating stages to bring the temperature back in line within the Normal temperature range (you can have up to 2 heat stages)

Humidify Setpoint - if the RH reading is below this parameter, the condition is considered too dry, and the system will go into the humidification stage.

Dehumidify Setpoint - if the RH reading is above this parameter, the condition is considered too damp, and the system will go into the dehumidification stage.

C02 Setpoint - if the C02ppm level is blow this parameter, the condition will be Low C02, and the system will start injecting C02 until it reaches the Setpoint plus deadband.

Note:

* Temperature, Relative Humidity, and C02 can have up to 3 setpoints in a 24 hour time period.

* Start Times set for setpoints are the same for Temperature, Relative Humidity, and C02
